Pronunciation, writing, interviews, meetings — DevGlish handles every English challenge developers face. Select text and press ⌘⇧D to get AI-powered learning cards, or press it with nothing selected for a quick input box. 6 smart modes, AI quizzes, scenario practice, and spaced repetition — all from your menu bar.
As a non-native English speaking developer, you've probably mispronounced Kubernetes in a meeting, written "please kindly help" in a code review, or struggled to explain a technical decision in your second language. These small moments chip away at your confidence — even when your code is flawless. DevGlish fixes this by teaching you real developer English: correct pronunciation for 205+ tech terms, native phrasing for code reviews, standups, and Slack, plus L1 interference tips tailored to your mother tongue.
You learned these from docs, not conversations. That's why they sound wrong out loud.
| Term | Common mistake | Correct | Why |
|---|---|---|---|
| cache | "cash-ay" / "catch" | /kæʃ/ (like "cash") | Looks French, but English says "cash" |
| nginx | "en-jinx" / N-G-I-N-X | /ˌendʒɪnˈeks/ (engine-X) | Named after "engine X" |
| SQL | "ess-queue-ell" only | "sequel" or S-Q-L (both OK) | MySQL creator says "sequel" |
| sudo | "sue-doh" / "pseudo" | /suːduː/ (rhymes with "voodoo") | = superuser do |
| OAuth | "oh-auth" | /oʊˈɔːθ/ (Open Auth) | O = Open, not zero |
